Why was the ash from incense sticks effective in healing the scorpion sting, even though it wasn't the sacred Udi from the Dhuni?

The healing power in that instance came not from the substance itself, but from the immense faith behind the action. Chapter 33 explains that when Narayanrao couldn't find the real Udi, he used the ash from incense sticks but he *considered* it as Udi in that moment. It was this profound belief, combined with his prayer to Baba's image and chanting the Sai Nama mantra, that manifested the miraculous result. The text highlights that because the ash was 'considered as Udi from the path, such was the experience manifested,' proving that sincere faith was the critical ingredient.
